* Style sheet for the W3C specifications *
*
* Special classes handled by this style sheet include:
*
* Indices
* - .toc for the Table of Contents (<ol class="toc">)
* + <span class="secno"> for the section numbers
* - #toc for the Table of Contents (<nav id="toc">)
* - ul.index for Indices (<a href="#ref">term</a><span>, in §N.M</span>)
* - table.index for Index Tables (e.g. for properties or elements)
*
* Structural Markup
* - table.data for general data tables
* -> use 'scope' attribute, <colgroup>, <thead>, and <tbody> for best results !
* -> use <table class='complex data'> for extra-complex tables
* -> use <td class='long'> for paragraph-length cell content
* -> use <td class='pre'> when manual line breaks/indentation would help readability
* - dl.switch for switch statements
* - ol.algorithm for algorithms (helps to visualize nesting)
* - .figure and .caption (HTML4) and figure and figcaption (HTML5)
* -> .sidefigure for right-floated figures
* - ins/del
*
* Code
* - pre and code
*
* Special Sections
* - .note for informative notes (div, p, span, aside, details)
* - .example for informative examples (div, p, pre, span)
* - .issue for issues (div, p, span)
* - .assertion for assertions (div, p, span)
* - .advisement for loud normative statements (div, p, strong)
* - .annoying-warning for spec obsoletion notices (div, aside, details)
*
* Definition Boxes
* - pre.def for WebIDL definitions
* - table.def for tables that define other entities (e.g. CSS properties)
* - dl.def for definition lists that define other entitles (e.g. HTML elements)
*
* Numbering
* - .secno for section numbers in .toc and headings (<span class='secno'>3.2</span>)
* - .marker for source-inserted example/figure/issue numbers (<span class='marker'>Issue 4</span>)
* - ::before styled for CSS-generated issue/example/figure numbers:
* -> Documents wishing to use this only need to add
* figcaption::before,
* .caption::before { content: "Figure " counter(figure) " "; }
* .example::before { content: "Example " counter(example) " "; }
* .issue::before { content: "Issue " counter(issue) " "; }
*
* Header Stuff (ignore, just don't conflict with these classes)
* - .head for the header
* - .copyright for the copyright
*
* Miscellaneous
* - .overlarge for things that should be as wide as possible, even if
* that overflows the body text area. This can be used on an item or
* on its container, depending on the effect desired.
* Note that this styling basically doesn't help at all when printing,
* since A4 paper isn't much wider than the max-width here.
* It's better to design things to fit into a narrower measure if possible.
* - js-added ToC jump links (see fixup.js)
*
